AC SMPS Flyback Transformer EP-525SG RoHS Approval POE Midspan Application

I have had excellent support from Nick Chou at Shareway. We purchased some parts from him and he delivered the products on time and without incident.

—— Phil Hale -- CEO of PSwitches

I have worked with Nick Chou at Shareway for more than 5 years. The most impressive thing is you can always get quick response from him .

—— David Rosero -- CEO of Isolution Service Center

Hi, I am more than happy to confirm your quality is great and your overall business handle is top notch. You have always been an excellent and very accommodating company to us. If you need me to speak directly to them I am more than happy to do so.

Characteristic Parameters
working frequency

Transformer core loss has a large relationship with frequency, so it should be designed and

used according to the frequency of use. This frequency is called the working frequency.
rated power


At a specified frequency and voltage, the transformer can operate for a long period of time

without exceeding the output power of the specified temperature rise.
Rated voltage
Refers to the voltage that is allowed to be applied to the coil of the transformer and must not

be greater than the specified value during operation.
Voltage ratio
Refers to the ratio of the primary voltage to the secondary voltage of the transformer, which

has the difference between the no-load voltage ratio and the load-to-voltage ratio.
No-load current
When the secondary of the transformer is open, there is still a certain current in the primary.

This part of the current is called no-load current. The no-load current consists of magnetizing

current (generating magnetic flux) and iron loss current (caused by core loss). For a 50 Hz

power transformer, the no-load current is substantially equal to the magnetizing current.
Load loss
Refers to the power loss measured at the primary when the transformer is open secondary.

The main loss is the core loss, followed by the loss (copper loss) of the no-load current on

the primary coil copper resistance, which is small.
effectiveness
Refers to the percentage of the ratio of the secondary power P2 to the primary power P1.

Generally, the higher the rated power of the transformer, the higher the efficiency.
Insulation resistance
It indicates the insulation performance between the coils of the transformer and between

the coils and the iron core. The insulation resistance is related to the performance of the

insulating material used, the temperature and humidity.
